IMPROVEMENT IN MACHINES FOR MAKING HYDRAULIC AND OTHER HOSE PIPESlSpecification forming part of Letters Patent No. 173,6 l6, datedFebruary 15, 1876 application filed October 25, 1875.

. To all whom'z't may concern Be itknown that I, JAMES E. GILLESPIE, ofBoston, in the, county of Suffolk and State of Massachusetts, haveinvented an Improvemerit in Machines for'Manufacturin g Hydraulic andother Hose Pipe, of which 'thefollowing is a specification:

This invention relates to a mechanism for manufacturingindia-rubber-lined hose for hydraulie and other purposes, and is animprovement on Patent No.163,925, June 1, 1875, granted to me. -,In suchmachine the warp-carriers have pivoted inclined feet adapted to fitgrooves in a rotating surface or plate, and the feet cross each other.as the carriers are moved by the action of the plate to form sheds inthe warp for the passage of the weft-threads that pass through guidesprojecting from the rotating plate and adapted to lay their threads aswefts between the warps. 1

. In this present invention like carriers and feet are employed, andthey operate in the grooves in the plate in the same way, but thestruction of the plate forms one feature of this in ven tion;

The invention also consists in a tension device supported on the carrierand adapted to bite and hold the warp-thread until-released V by thecarrier-weight; also, in mechanism to fold a piece or strip ofindia-rubber, or its equivalent, about a mandrel, into which steam maybeintroduced,'lapping one edgeof the strip over the other, the lappingbeing in the direction of the length of the tube, and in connection withsuch an apparatus I employ A, a mechanism for weaving a fibrous coveringover the india-rubber, to be formed'as hereinafter set forth.

Figure I'is a side elevation of a machine embodying, this invention.Fig. 2 is a top viewof 'the warp-carrier-operating grooved plate; Fig.8, a carrier detached and enlarged; Figs. at and 5, views of thewarp-tension device; Eigs. 6 and -7, th e weft-tension; and Fig.

8, a detail of the mandrel, over which the tube is formed.

In this invention the frame of the loom is of of the hollow shaft issecured a hub, I), having projecting therefrom a rest-plate, 11 on alevel with the top plate a, and provided with holes 0, for attachment ofthe forked warp-carrier guides 0 each guide being held by a screwpassing therethrough and into the holes 0. In Fig. 2 is shown in dottedlines one pair of these guides. These guides receive the heads 0 of thewarp-carriers, one shown detached in Fig, 3, and the pivoted feet (1project into grooves d 61 formed in the warp-carrier-actuating plate 6,arranged at top of a sleeve 0, provided with a gear, 6 and fitted aboutand so as to turn on the hollow shaftc the plate 1 6 deriving motionfrom the gear fon the main shaft f, operated in any suitable way.v Thisplate 0 carries the weft-guides f the pivoted feet (1 rest in thegrooves d (1 and,as the plate rotates, the warp-carriers are crossedfrom one guide, a, to its opposite guide and across the groove betweenthe ends of the carrier guides, in which the weft-guides travel, all inthe manner described in the patent referred to, to which reference ismade, the warp and weft threads passing over the cup 9, also used insuch patent, and provided with a pipe, supplied with liquid or plasticindiarubher, or its equivalent, or suitable water-proofing or cementingmaterial, to be forced through the pipe 9- into the cupg, and againstand between the india-rubber lining g and outer woven covering h. Inthis instance the cup 9 is separate from the mandrel. 7L about which theindia-rubber lining is formed, and the fibrous covering is woven, and itis supported by the standard h -and the pipe 9 the latter passing outthrough the bottom of the shaft (0. (see Fig. 1,) and receiving itsindia-rubber solution from a proper source. The mandrel h is connectedby means of a projection, i, with the hub b and stands above andsubstantially in a line withthe opening in the hollowshaft c whileattached to another portion of'such hub by a projection, 1 is alongitudinally slotted folding guide, i, and the india-rubber lining ledinto the lower end of the hollow shaft of is folded about the mandrel hby means of the guide 1', surrouiuling, but not touching, the mandrel.

This rubber lining is shown in section-lines in Fig. 2, with-the mandrelwithin and the guide outside of it, the edges of the in'dia rubher beinglapped one over the other. A press er-roller,.j, on an adjustable arm,j, controlled by a screw 'i presses the lapped edges of the india-rubbertogether, such edges having been previously wet or moistened, preferablywith benzine or equivalent, or with suitable cement, to cause the edgesto unite firmly and form a water-proof sea-n1 or lap.

I may heat the inner sideof the mandrel or the guide by passing steam orwater through a pipe, as at k.

I intend to apply benzine, or a preparatio thereof, or other softeningmaterial, to the .edges of the india-rubber, during the process offolding, by means of a brush, or through a or water-pipek is led, andinside the chamber a is placed a pipe, 10 open at top, and into and fromthe open top of which, -and within the india-rubber lining, may be blownchalk or its equivalent, the same-being allowed'to drop and cover orcoat the inner side or surface of the lining material, to prevent itfrom sticking to the mandrel. After the lining is folded or made into atube the covering h is woven thereon, and a quantity of liquidindia-rubber,

or an india-rubber or cementing compound of any well-.known kind, orsuch as used when securing rubber within fibrous tubes, being expressedfrom an annular opening in the top of the cup 9, between the liningg andcovering h, the preparation forced between the lining and cover beingpreferably such a preparation of india-rubber as will vulcanize andcause a firm and close adhesion and union of the covering'and lining.

Referring to Fig. 2, the plate 0 is designed to rotate in the directionof the arrow there on; and it will be noticed that the ends I of thecrescent-shaped or dividing ledges l are sharper than the edges 1 andpieces m in, forming the walls of the groovesd d are undercut, as shownin dotted lines, Fig. 2, and between the ends I l are placed adjustablepieces m with friction-rollers n.

I When the part 0 of apivoted foot of a warpcarrier is to pass fromeither of the positions a of either groove to either position 01 or towas re cross the points where the two grooves inter sect, then one ofthe small anti-friction rollers a, or a projection on m meets theforward portion of the pivoted foot at one side, and throws it quicklyto the side of the end l farthest from it, the enlarged or thickened endl of the crescentshaped ledge 'l acting at the same time on the oppositeside of the foot, back of its pivotal point, throwing the free end ofthe foot quickly away,'or so that it passes into the cut-away orrecessed parts of the walls of the pieces m or W, thereby rendering thecrossing of the feet from one part of the groove to another part morerapid and certain, thereby preventing the carriers from dwelling so longas to become caught when passing from an outer to an inner carrierguide,and crossing the usual circular groove or path w, in which theweft-guides move.

With this-construction the carriages are changed more rapidly thanusual, and the loom may be run faster. Each warp-thread passes from aspool, 0 through a hole in a guide, 0 on which (and free to slide) is acarrierweight, 19, provided with a roller, 12. A tension-lever, p", ispivoted to the guide 0 and a spring, q, acting on the adjusting screw ordevice q bears the shoulder g (see Fig. 4) of the lever 19 with thedesired force against the warp-thread which passes between the guide 0and shoulder The warp, after passing through the hole in guide 0, ispassed between the shoul ,der q -and the guide, then over and in thegrooved portion 1' of the lever 21 about the roller 12 over the roller4" to the weavingpoint. The weight 19 takes up and holds the slack warp;but when the slack is used up the weight is raised, and strikes the endof the lever, rocks it, and releases the warp from the action of thelever, and, after the formation of enough slack warp, the weightdescends, releasing the lever and the spring q, then moves the lever tobite the thread.

A detail of the weft-tension is shown in Fig. 6. Each weft-thread passesfrom a spool,

s, over and about a tension device composed.

of a truncated cone, 8 with a connected hub, 8 The weft is wound fromthe larger to the smaller end of the cone so as to gradually crowd thecoil down the cone, yet not to permit thestrands to overrun each other.

About the hub is placed ayielding com-' pensating strap, t, preferablyof light metal, one end being fixedand' the other being passed through aslot or opening in a standard, t

whereit is provided with a spring, t one endname V e hereto the hub, thespring willyield and-allow the tensiondevice or wheel toturn, and thestrap being then loosened will allow the 7 wheel and hub to move.

This device is applicable for use as'a ten sion for the thread in ase\ving{n1achi11e, In-

- (see dotted lines,) I may make the grooves or paths more or lessirregular or cam-shaped, and the crossings may take place at any desiredintervals, the free ends of the inclined. pivoted feet being adapted tobe swung by the projections and ends. 1 of pieces 1 or equivalent piecesof other than crescent-shape between the grooves, the free ends of thepivoted feet passing intothc spaces cut away in the side walls of thegrooves;

It is evident the angle formed by the grooves at theircrossings maybe,under this arrangement, more or less sharp.

ltwi'll be understood that at thecrossing points of the grooves, asherein shown and described, the grooves'do not in curvature accord withthe curve of the pivoted feet, and the spaces formed bycutting away thewalls of the grooves permit-the ends of the feet to move therein.

1. The warp carrier-actuating plate, its projections 01., pieces at W,and ends '1 PM different sizes, in combination with the warpcarriers andthe inclined pivoted feet to operate the carriers quickly, substantiallyas described.

' 2. The combination, withthe warp'oarrier, of an adjustablethread-holding or nipping device, and a weight to operate thethreadholder, substantially as described.

3. A guide and mandrel to form and fold a lining of india-rubber, andwarp and weft' carriers adapted to weave a tubular covering about thelining, in combination with a cup to deliver a rubber or other cement onthe outside of the folded lining.

4. The cup and steam-heated mandrel, sep

arated therefrom, butwithin the cup, in combination with apipe'for'discharging chalk or equivalent within the folded lining,substan- ,,tially asand for the purpose described.

5. A guide and mandrel adapted to fold .a

strip of india rubber into tubular form, in.

combination with a cup to contain liquid rubber to be expressed orapplied to the outside of the folded rubber tube, substantiallyasdescrib'ed.'

6. The mandreland folding guide adapted to fold and lap' the edges of astrip of indiarubber, to form a' tube in combination with warp and weftcarriers and mechanism adapted .to operate them, to weave a tubularcovering on the folded and lappedtube, substantially as described.

7. The carriers and inclined pivoted feet connected at one end with thecarriers, in com-' bination with a grooved plate having the side wallsof the grooves cut ,away below the top surface of the plate, to receivethe free ends of feet thrown into such open spaces, when the curvatureof the grooves does not accord in curvature with the foot.
